Description of the Invention: The present invention relates to a device for degassing dust during the production of a synthesis gas which usually occurs in a coal gasification reaction, and the synthetic gas used herein has a broadly varying purity and is used. Gas mixtures of different chemical compositions, in addition to carbon monoxide and hydrogen, typically also contain carbon dioxide, nitrogen, hydrogen sulfide, and other components in varying combinations. The dust is degassed so that the toxic gases contained in the dust are completely no longer harmful to the environment. The offgas thus obtained can be collected by the apparatus and discharged by the system. According to the present invention, it is possible to utilize the residual heat contained in the dust and the dust obtained by the cooling. During degassing, the pressure of such dust is reduced by the apparatus from a high pressure level that is generally prevalent during the coal gasification reaction to normal atmospheric pressure. The invention is thus also related to a process whereby dust from the synthesis gas can be scrubbed and completely or almost completely degassed. Thermal gasification of solid fuels such as broadly variable coal, peat, liquefied residue, other residues, waste, biomass, and fly ash, or mixtures of these materials, is carried out under elevated pressure and elevated temperatures, and A high energy content and/or a target for producing a raw synthesis gas in a composition suitable for use in subsequent chemical compositions. The original syngas system is filled with fly ash which is derived from the fly ash content of the fuel supply. The fly ash is in the form of microparticles which need to be separated prior to subsequent use. In the case of dry separation, such as in a cyclone or a filter, the very fine granular solids are usually accumulated before being discharged from the pressure chamber. Originally, there is a gas in the void fraction of the accumulation of particles, and in this case +, the original syngas that is discharged is 201012918. Prior to final storage or removal, the solid must reduce the pressure and still remove the original synthesis gas in the void fraction.

US Patent No. 2007/00841 17A1 describes another production process for synthesis gas that continuously directs synthesis gas obtained from a coal gasification reactor through a system for mixing with a cooler external gas, and illustrates A heat exchanger and a dust separator. The dust separator can be equipped with a feeding device for purifying the milk. There may be several subsequent dust separators downstream of the pressure drop system to achieve a larger throughput. This allows a bulk fly ash to pass through at a time interval of overlap with a purge gas to facilitate removal of the unwanted gas during emptiness and filling of the feed hopper. This stripping process will be treated as a time decision step. The established process provides for the permeation of the fly ash stack to exclude any residual raw syngas components. One of the main reasons why the established process takes a long time is that during the action, in the opposite direction to gravity, the channel is usually formed. When the gas velocity is increased, due to the fine particle size of the fly ash, The gas passes through the channels. Due to this uneven permeation, the amount of time it takes to exchange the gas in the entire void fraction increases. In the opposite direction of gravity, in the period of permeation; due to the compaction of the fine particles and the consequences of the production. J network flows P and the risk of force during the emptying or removal of the feed hopper This is the purpose of providing a device that progressively returns the fly ash from the synthesis gas to atmospheric pressure and removes the synthesis gas contained in the fly ash 7 201012918. The purpose of the process performed using the apparatus is to also exchange and return the gas which accumulates in the pressure drop vessel and the precipitator during the emptying and filling process. The invention achieves the purpose of degassing dust from a synthesis gas produced by a gasification process in the form of a device comprising: • a primary dust separator, • a multipurpose container, • for degassing And cooling fluid, • a storage device for dust, • the synthetic gas produced is directed to a main dust separator via a connecting pipe, the dust-removed raw syngas gas stream and dusty solid helium are The dust separator is removed, the dusty solid still contains the original synthesis gas in the gap between the dust particles, • the dusty solid is directed into a multipurpose device equipped with means for reducing the pressure level The vessel is such that an off-gas is obtained and a solid containing a lower amount of gas in the void fraction is left, • a means for transporting the solids into the gas exchange apparatus, the gas exchange apparatus comprising: • a gas exchange tank, • a dust separator, • a feed device for exchanging gases, • it may reduce the gas exchange tank to atmospheric pressure, • The gas exchange apparatus has an outlet for a solid that has been at least partially released from the original synthesis gas, 201012918. The gas exchange apparatus has an upwardly directed conveyor belt, a gas and solid particles directed upward Flow energy is established in the conveyor belt, the conveyor belt has an open cross section, a bottom effective section and a top effective section, and the bottom effective belt surface of the conveyor belt is enclosed in a gas exchange tank close to the bottom, The exchange gas feed device leading into the effective section of the bottom is clamped below the bottom end of the conveyor belt, and the dust separator is such that it can flow with gas and solid particles from the helium gas exchange tank. The supply is connected, and the dust separator has a discharge device for the exhaust gas flow and a downward guide connection device for entering the gas exchange groove for a solid released from the raw synthesis gas. An embodiment of the apparatus is contemplated at any point in the processing flow. There is also a heat exchanger. The heat exchanger is designed as a cooler and is positioned such that its cooling surface is in contact with the dusty solid. Preferably, at least one such cooler is located in the gas exchange apparatus. Within the apparatus, the &-cooler is located in the process flow or directly in the gas exchange tank between the dust separator and the gas exchange tank; various combinations are also possible. Other embodiments of the apparatus envisage that the dust storage device has a pressure equalization m system coupled to the gas exchange device t dust separator; the gas exchange tank and the dust separator may also form a single structural unit. The invention further achieves the purpose of removing the ash 201012918 from a synthesis gas by a process, the synthesis gas is produced by a gasification process, and usually contains carbon monoxide and hydrogen 'and ash and dust particles, wherein The syngas system is guided through a connecting pipe into a main dust cutter. Most of the dust is separated in the main dust separator. • Once the dust has been separated, the solid particles flow in the same The pressure level is directed into a multi-purpose container that reduces the pressure in the multi-purpose container such that a tail gas stream is obtained and a solid containing a lower amount of gas in the void fraction is left. The solid particle flow is pneumatically guided from the multi-purpose container into a gas exchange device by means of a carrier gas, and 'a solid circulating particle stream is produced in the gas exchange device by means of an exchange gas, and the exhaust gas released Thereby it is discharged via a dust separator. For this cooling, in the connection between the dust separator and the gas exchange tank, other embodiments of the process envisage that the dust is cooled in the process flow. It is also conceivable that the dust is cooled in the gas exchange tank. Another embodiment of the process envisages that the transport density in the transport line between the multi-purpose container and the gas exchange tank is less than 75 percent of the bulk density of the dusty solid. Another embodiment of the process envisages removing the batch processing in the gas exchange tank in the multi-purpose vessel by adding an exchange gas simultaneously with a portion of the next batch of voided gas. Alternatively, the selection system, other embodiments of the process envisage forced exchange into the 201012918 multi-purpose vessel, one or both of the gas exchange tanks, continuously or batchwise, cyclically or beatingly It was added during the gas exchange process. Another option is that the other embodiment of the process envisages that the added exchange gas system is accompanied by at least a portion of the raw synthesis gas in the void space, from the multi-purpose container or one of the gas exchange tanks. Or discharge continuously. In all cases, the joining and discharging operations can be carried out separately and continuously or in batches, which is an advantage of the invention due to the process flexibility thus achieved. Other embodiments of the process relate to gases leaving the apparatus. Here, it can be envisaged that once the exchange gas has been separated by the circulating solids and has left the gas exchange device, the exchange gas system added to the gas exchange tank is fed with at least a portion of the original synthesis gas in the void space. Enter into a disposal unit. It is also conceivable that the gas system discharged from the multi-purpose container is fed to a disposal unit. It may further be envisaged that once the exchange gas has been separated from the recycle solids and has exited the gas exchange apparatus, the added exchange gas system feeds the raw synthesis gas to a combustion reactor along with at least a portion of the void space And the gas system discharged from the multi-purpose container is fed to a combustion reactor. It may further envisage, after separation from the circulating solids and after exiting the gas exchange apparatus, the exchange gas with which at least a portion of the raw synthesis gas is added, or the gas discharged from the multipurpose container, Or the two gases are first fed to a gas reservoir for buffering and equalization. The described apparatus and the described process provide the advantages of rapid and complete degassing of fly ash from a coal gasification process 11 201012918. The described process can significantly reduce the time required for degassing of fly ash. The apparatus according to the invention is illustrated on the basis of three figures, which are merely examples of the design of the apparatus according to the invention. Figure 1 shows the entire part of the apparatus for the degassing of dust downstream of the outlet nozzle designed for synthesis gas. Fig. 2 shows a gas exchange device 21 having the gas exchange tank 1 and the associated dust separator 13. Figure 3 shows a gas exchange tank with an integrated dust separator 13 10 ° The pressurized raw synthesis gas containing fly ash 1 is directed into the fly ash separator 3, which can be designed as a Filter or a cyclone separator. Thus, a dust-removed syngas Zhao 2 and fly ash 4 are obtained, which is guided into the multi-purpose container 5. In doing so, it is inevitable that a small amount of the raw synthesis gas in the void fraction of the particulate accumulation also enters the multipurpose container 5. In the multi-purpose container 5, the pressure of the fly ash which is still pressurized is reduced. The batch of solids 7 is then transported into the gas exchange tank 10 of the gas exchange unit 21 via a pneumatic conveying line 9 by the addition of a carrier gas 8. In order to compensate for the volume of solids transported by the multi-purpose container 5 and to maintain the high pressure in the multi-purpose container 5, the exchange gas 6 is fed into the multi-purpose container 5'. The multi-purpose container 5 is discharged during the fly ash. It has the function of a hair dryer. When the offset has been transported to the gas parent shifting tank 10, the exchange gas 11 is added such that a gas and solids stream 12 directed upwards is followed by 12 201012918. The gas and the m-body particle stream enter a fraction, and the @ system is separated by the gas in the separator, so that the solid 14 is returned downward toward the starting point where the gas and solid particles are directed upward. Stream 12 is produced by the addition of gas 11. In this way, the circulation of the solid is achieved, the circulation of the solid can be controlled via the geometry of the gas exchange tank 10, and in particular via the gas feeder 11. The gas that has been released from the solid exits the gas exchange tank in one of a continuous or batch mode. In fact, the simple standard permeation requires a considerable amount of time, because the very fine dust particles are only achieved by non-ideal permeation, such as channeling and blocking. Between the accumulation which has been relaxed by the movement of the solid and the added scrubbing gas, an optimum gas mastering is achieved in accordance with the present invention in combination with a flow of scrubbing gas and circulation of the solid. The strong upward particle flow of the solid ensures that the gas in the void fraction is optimally exposed to the exchange gas and to mix the two. The desired or acceptable residual concentration of the raw syngas component in the void fraction can be readily achieved by the number of cycles of the solids 11 added. The following is the separation of the original synthesis gas. In most cases, the temperature of the solid is too high to be stored or removed even after it has been transferred to the gas exchange tank. Accordingly, a heat transfer device is provided which contacts the solid of the cycle and dissipates heat to achieve a target temperature of the solid. In this example, this is the heat exchanger 丨5. The fly ash that has been degassed to this maximum extent is obtained by the gas exchange unit 21 and fed to a cylindrical chamber 17 via a discharge system 16. The circle 13 201012918 The silo 17 is equipped with an equalization line 2〇 which returns the gas displaced during the filling to the dust separator 13. Further, an exhaust gas 18 obtained by the dust separator 13 is treated in the same manner as the dust-removed exhaust gas 19 obtained by the multi-purpose container 5. Figure 2 shows an external solids circulation loop. Here, the upwardly directed gas and solids stream 12 from the gas exchange tank 10 is directed to a dust separator 13 by the addition of the exchange gas 11. Here, the solid is separated by the gas. The gas includes a mixture of the exchange gas U of the added person and the gas from the void portion of the particles. The gas mixture 18 is brought into the treatment unit. The separated solid flows downward in the direction of gravity toward the gas exchange tank 1G. A flat plate type heat exchanger 15 is designed as a heat transfer surface in the downward flow of particles to dissipate the heat of the solid. Figure 3 shows the same principle, but with an internal circulation, i.e., the flow of solid particles circulates within the gas exchange tank 1〇. In this case, the gas exchange tank 1 () according to Shuming's equipment is equipped with an integrated dust separator 13. Again the 'heat transfer surface is provided for cooling the solid. A two-layered wall for heat transfer 'in the form of a cooling jacket is provided as a heat exchanger 15 〇 In this case, the heat transfer surface of the tester It is immersed in the circulating solid during operation. Other examples mention the mode of operation. In the preferred process mode, the multi-purpose container 5 is used simultaneously with the batch processed first in the gas exchange tank 1G to reduce the pressure that will be accepted under a batch, and then the void share gas escapes. And then, during the remaining time of the brakes, the M # is again used by the gas to enter the pipeline 6 to promote the force, in order to take over the v East and then immediately reduce the pressure. Adding 201012918 Dust effect causes dilution of the original synthesis gas content of the eyebrows ^ ^ , ^ in the void fraction; reduction of pressure enthalpy (4) followed by the portion of the gas mixture. Depending on the time available, the program can be repeated by a number of Μ ^ , owing to some of the original synthesis: the system is excluded from the (four) share, even before the solid batch is shipped to the body exchange tank 10 for processing. This reduces the number of cycles of the gas, body, and thus shortens the cycle time. Therefore, a larger number of flying squares of each side of the unit's station, β#, 00b, are released from the original synthesis gas and 7 P, which has the single pipeline configuration. The use is referred to herein as a multi-purpose container 5 because it has a variety of uses. First, JL Straight Female _ . The bottom of the process feed, used to take the bulk of the solids at the level and used to reduce this level of force. Its::: one: the role of the first washing stage, by the pressure of the circulation and: less pre-removed part of the original synthesis gas from the accumulation, the body has a blowing container in the two slots, It is used for pneumatic transport to the main washing stage in the gas shifting tank. The inert gas exchange gases 6 and 11 and the carrier gas 8 may also include, for example, nitrogen but air, carbon dioxide or the like may also be used. If the gas stream 18 is directed to a post-combustion unit, such as air consumption. " Changing the gas U can be advantageous, and also contributes to reducing the inert gas consumption, which is not apparent for the downstream disposal units of the exhaust gases 18 and 19 - the advantage is that the main operation is almost continuously:: Interrupted, the lower-batch is carried during the time two = then the belt is transported. This result is based on the quantity, and an almost exhausted 18 gas flow occurs almost 15 201012918. From the viewpoint of the process, the processing system is easier than the case where the number of peaks occurred during the operation. Another advantageous process variant of the pre-wash stage is that the batch is not reciprocally pressurized with an exchange gas cycle and then reduced in pressure, but is pressurized at a constant pressure with a continuous stream of particles. Thus, there will be no peaks in the descending gas flow, and the treatment unit for the tail gas streams 18 and 19 will be pressurized by the continuous stream of particles from the pre-wash stage and the main wash stage.
